Abstract: PROBLEM TO BE SOLVED: To prevent the generation of abnormal sound by equalizing the shapes of the arcs of the roll of a damper supporting a voice coil and the roll of an edge thereby preventing amplitude from being restricted by the roll shorting arc length at threshold amplitude at the time of a large input. SOLUTION: An edge 1 in the form of an arc RE with a single upper roll and the damper 2 of an ark length RD with an upper roll in the same shape as the edge 1 are provided to hold the voice coil 4 respectively fixed to a dome- like oscillator 3. At this time, the arc lengths of the damper 2 and the edge 1 are respectively equally R. At the time of taking a threshold amplitude L straightening the ark of the edge 1 upward at this oscillation system, the edge 1 and the damper 2 are respectively expanded and the threshold amplitude L at the time depends on the arc lengths R of the edge 1 and the damper 2. Consequently, thrusting sound at the time of largest input is eliminated by equalizing the arc lengths R of the edge 1 and the damper 2 and nearly equalizing a shape size for equalizing the threshold amplitude and a largest amplitude.

Abstract: PURPOSE: To improve the utilization efficiency of the light of a lamp without changing the lamp by forming a partial rotating paraboloid or an elliptic surface of a reflector for abutting on the shape of an incidence port of multiple step formed collected reflecting surfaces having a different dimension. CONSTITUTION: An inner reflecting surface of a reflector 1 is formed of multiple partial rotating paraboloid surfaces and ellipsoidal surface formed of step formed bulk material for abutting on an incident rectangular port. Light beams projected from a front surface of each partial curved surface onto an arc triangle projection surface become parallel with each other in the case where the curved surface is paraboloid, and positional relation between the lamp 2, of which light is converged to a second focal point, and a curved surface of the reflector 1 is maintained in the case where the curved surface is an ellipsoidal surface.  Since each partial rotating curved surface is positioned with a stage difference between other partial rotating surface adjacent to the incident rectangular port at position for fit-on and having a different radius and a stage difference part is formed of a surface in parallel with the outgoing light from the lamp, the light is converged independently of the stage difference part, and generation of bad influence such as irregular reflection is prevented. With this structure, utilization efficiency of the light is improved, and a brighter image can be obtained without changing the lamp.

Title: Method for forming color filter
Inventor: TERAO YOSHITAKA
IPC: G02B5/20
Filed: 1990-11-22
Abstract: PURPOSE:To improve a yield of electrode formation on a gas discharge display panel through prevention of production of a stepped part between color filters by embedding a filter material in an embedding hole by a thick film printing method to form a thick film filter. CONSTITUTION:Embedding holes 48G and 48B are formed in a base by a sand blast method and a filter material is embedded in the embedding holes by a thick film printing method to form thick film filters 40G and 40B. Height by which the thick film filter is protruded from the base is reduced by increasing the depth of the embedding hole. Thus, when the thick film filters 48G and 48B and a colored filter 40R formed by an ion exchange coloring method are formed on the same base surface, even when the thick film filter is formed in a desired thickness, through regulation of the depth of the embedding hole, height by which the thick film filter is protruded from the base can be adjusted to approximately the same value as that of the filter 40R. A clear filter protection layer 52 is formed on the color filters 40R and 40B, and an anode 56 is formed thereon. In this case, since a difference in a stage between the color filters 40R and 40G, 40B is hardly produced, and no stepping of a clear conductive film 54 is formed, resulting in prevention of disconnection of the anode 56.
